BTW -- can you go ahead and check in the two testcases for the latent
bugs that you found while working on killing LOOP_EXPRs?  The first
being the test for removal of unreachable blocks containing BIND_EXPRs
which reachable children and the second being the insert at the end of
a block which happens to be a BIND_EXPR.
